Whale Watch
Every morning, the three highest-conviction whale moves the monitor caught overnight — what moved, how big, and Whalur's verdict.

Whalur hunts for repeatable, statistically significant market mechanisms — behaviors that produce positive expected value across many securities and market conditions — and turns them into ranked, explainable signals.
Plans from $29.99/month. Whale Watch, Whale Moves and Markets are free to read.
Whalur isn't a list of hot tips. Every idea is tested on years of real market history, then judged on recent data it has never seen, and almost everything gets thrown out. What survives is what you see.
Writes brand-new trading ideas every night.
Invents and tests ideas around the clock, and keeps only the ones that still work on data they've never seen.
Re-tests every idea against every stock, every night.
An AI analyst that digs into the best ideas to find exactly where they work.
Checks how every idea behaves in calm markets and fearful ones.
Fires a whale move the moment a tested idea triggers on a real stock.
Re-tests every idea on the last 12 months, so you see what's working right now.
Calls the week ahead for every stock, then grades itself against what actually happened.
Type any market hunch in plain words and get an honest verdict: real, maybe, or luck.
Type it in plain words: “when oil crashes, banks rally the next week.” Our AI analyst turns it into one fair test, locks the rules before it looks, runs it on 25 years of real prices (back to 2000), then checks it again on 2025–26 data it never used. Most hunches turn out to be luck. Now you'll know which ones aren't.
Latest hunches
A whale move is our name for a signal: big investors ("whales" — funds and institutions) can't buy or sell without leaving footprints, like a burst of trading volume or a sharp push in price, and Whalur's tested strategies watch for those footprints and for market conditions such as VIX fear or swings in rates and oil. When one fires on a stock, that's a whale move.

News, chart patterns, and hot takes feel actionable, but few survive honest measurement. Trading them is paying for randomness.
A strategy optimized on one stock in one regime collapses the moment conditions change. Curve-fitting isn't research — it's rehearsal for a loss.
A 70% win rate with ugly losers still bleeds money. The only number that compounds in your favor is expected value — and almost nobody measures it.
Not “what stock should I buy?” but “what measurable market behavior is occurring right now, and what has history demonstrated is the highest-expected-value response?”
A hypothesis engine generates and evaluates thousands of parameterized strategy variations — order-flow continuation, exhaustion, liquidity imbalance, mean reversion, and more — against historical market replays.
Candidate mechanisms must hold up across bull and bear markets, sectors, market caps, volatility regimes, and execution-cost assumptions. Whatever fails is discarded — before it costs anyone money.
Live signals arrive with a confidence score, the historical EV of similar setups, and the reasoning behind them — so you always know why, not just what.
Whalur continuously measures a curated research universe of ~60 representative stocks: relative volume, VWAP distance, liquidity, persistence, volatility, and dozens of other reusable features.
The hypothesis engine runs each candidate mechanism through historical replays — long and short, multiple entries and exits, position-management variants — and measures expected value, not anecdotes.
Survivors are re-tested across market cycles, sectors, capitalizations, and cost assumptions. Only mechanisms that stay positive everywhere advance to live monitoring.
Validated mechanisms are monitored in real time. Every alert is scored, explained, archived, and fed back into research — so the system gets sharper with every trade it observes.
Whalur's guiding principles are non-negotiable: expected value over win rate, robustness over optimization, repeatability over isolated success, and universal mechanisms over ticker-specific folklore.
“Rather than asking what stock to buy, we ask what measurable behavior is happening right now — and what history says is the highest-EV response.”
Our promise: no signal ships until its mechanism has survived robustness testing — and every live signal is tracked against its historical expectations, in the open, inside your dashboard.
Each house book opens and closes positions from live signals using the hypothesis's own exit rules. Every number is measured against SPY over the same days.
Paper trading: simulated fills at the signal day's close, 5 bps cost per side, no real money.
No. Whalur is a research platform that discovers and validates market mechanisms. When those mechanisms fire in live markets, you get ranked, explained signals — the evidence, not just a ticker.
A strategy that wins 40% of the time can be highly profitable if winners outweigh losers. Whalur measures the average outcome per trade across many samples — the number that actually compounds — instead of chasing high win rates that hide fat losses.
A whale move is our name for a signal: big investors ("whales" — funds and institutions) can't buy or sell without leaving footprints, like a burst of trading volume or a sharp push in price, and Whalur's tested strategies watch for those footprints and for market conditions such as VIX fear or swings in rates and oil. When one fires on a stock, that's a whale move. Every whale move is published on the free Whale moves page, and the three most confident each day make up the Whale Watch email.
The roadmap includes Alpaca integration for paper trading and automated execution with position sizing and risk controls. Execution always remains driven by validated research — never discretionary calls.

One email a day. The three highest-conviction whale moves the monitor detected, what Whalur's call on each one is, and a link straight to the full entry, stop and target. Three moves and the calls behind them — nothing else.
